y Arm/mns HENRY AUGUSTUS TUCKETT AND VICTOR A. HELLSTROM, OF SALT LAKE CITY, UTAH.

SCIRAIPIER.,

To all whom it may concern.'

Be itknown that we, HENRY A. TUoxnT'r, a citizen of the United States, and VICTOR A. IIELLs'rRoM, a subject of the King of Sweden, and both residents of Salt Lake City, in the county of Salt Lake and State of Utah, have invented a new and Improved Scraper, of which the following is a full,`

Figure 1 is a sectional elevation of the invention showing the position of the blades when the scraper is moving in one direction; Fig. 2 is a view similar to that shown in Fig. 1, but with the positions indicating how the blades are disposed when the scraper is moved in the o-pposite direction; Fig.` 3 is a plan view of the invention; and Fig. 4 is a sectional view showing how the scraper blades are adjustably secured to the studs journaled in the frame.

By referring to the drawings it will be seen that a frame is provided having sides 5, side bars 6 engaging the said sides and a central bar 7, which also engages the sides 5, the sides of this central bar 7 converging outwardly. Journaled to the sides 5 of the frame there are studs 8 in which there are orifices 9, bolts 10 being disposedin the said orifices 9 and in slots 11 in the scraper blades 12'for adjustably securing the said scraper blades 12 to the studs 8, the said scraper blades l2'extending one at each side of the Specification of Letters Patent. Patented June 15, 1915,. Application filed August 26, 1914. Serial No. 858,633.

Y Vcentral bar 7, and each between the said central bar 7 and one of the side bars 6.

As will be seen by referring to Figs. 1 and 2 of the drawings, the inner sides 12a and the ends 12b of the scraper blades 12, form obtuse angles, so that when one of the scraper blades 12 is positioned to scrape the surface which is being treated, the coinpanion scraper blade 12 will have its end 12b disposed flat against the said surface for sharpening its cutting edge 12.

It will be understood that with our scraper, the surface which is being treated, may be scraped when the scraper is moved in either direction and that at all times when one of the scraper bladesy is in operative position and is scraping the surface to be treated, the companion scraper blade will have its cutting edge sharpened to be used on the return stroke of the scraper.

Having thus described our invention we claim as new and desire to secure by Letters Patent:

1. In a scraper, a frame having two openings disposed side by side and two scraper blades, one extending through each of the openings and pivoted to the frame for engaging the frame openings.

2. In a scraper, a frame having two openings disposed side by si de, two scraper blades pivoted on axes extending longitudinally of the openings, the blades extending through the openings with their outer terminals forming obtuse angles at their inner sides.

3. In a scraper, a frame having two openings disposed side by side, and two scraper blades, one extending through each of the openings and pivoted to the frame on axes Y extending longitudinally of the openings for engaging the frame at opposite sides of the openings.

4. In a scraper, a frame having three substantially parallel bars, two scraper blades pivoted to the frame on axes substantially parallel with the bars, the blades being sepaat opposite sides of the rated by one of the bars and being each disposed between two of the bars, the outer end of each of the blades forming with its inner side an obtuse angle.

5. In a scraper, a frame having an opening, a scraper blade having a terminal pro,- jecting through the opening7 the scraper blade being pvoted for striking the frame at opposite sides ot the opening, the outer` edge of the terminal forming with the side of the scraper an obtuse angle, the apexy of which is substantially parallel with the axis of the scraper.
